Tenshin-Sama

Japanese name:

天心様

Tenshin-Sama is an old sage living aboard the Zanbani, who acts as a guide for Nakiami, Raigyo, and Akiyuki. She rarely leaves her quarters and often keeps both of her eyes closed, occasionally opening one eye when speaking. Her closed eyes are perhaps a medical condition as Raigyo, upon his return, gives her "Eye medicine, carefully prepared, taken from the Shitogi Grassland."
